'The Walking Dead' in memoriam: Most shocking deaths

Image Comics

"The Walking Dead" is not the only current TV show known for killing off major characters. ("Game of Thrones," "Downton Abbey," "Grey's Anatomy" and "Revolution" come to mind, among others.) But no other show does it as frequently or ferociously as AMC's smash hit post-apocalyptic drama. Shocking deaths are built into the fabric of the storytelling from Robert Kirkman's comic books, but the series stands on its own in order to keep fans guessing about who lives and who dies. Take a look back at the most memorable and shocking deaths of the first three seasons of "The Walking Dead."
